I refuse to use capitalone.com on my computer until they fix it. I mean, that's the login page.
I noticed this because I use noscript, and the only domain I should have to open up for that page is capitalone.com, yet for some reason (that I have been too lazy to track down), it also wants 127.0.0.1 and...whatever your router is. Feel free to double-check for yourselves, I would love to have outside corroboration. And if it is just me, I'd like to know that, too, for obvious reasons.
